Manganese-mediated reductive amidation of esters with nitroarenes

Xile Hu, Peng Wang, Chi Wai Cheung, Ning Shen

Amides are ubiquitous molecules in nature and in synthetic chemistry. Here we report a convenient and efficient method to synthesize N-aryl amides via amidation of esters with nitroarenes. In the presence of manganese metal, this amidation proceeded smooth ...

Organocatalysts in C-N Bond Forming Reactions of Amines with CO2

Martin Hulla

The thesis describes a simple approach for N-formylation of amines with CO2 and hydrosilane reducing agents, the use of organic salts as N-formylation catalysts, their physical properties required for high catalytic activity and their role in the catalytic ...

Data-Driven Model for the Dynamic Characteristics of O-Rings for Gas Bearing Supported Rotors

Jürg Alexander Schiffmann, Philipp Kaspar Bättig

The measurement results of various nitrile butadiene rubber (NBR) O-Ring sizes are pre-sented, and reduced-order models are developed in order to predict the stiffness and damping coefficient as a function of O-Ring geometry, Shore hardness, squeeze, and e ...

Formal Aza-Wacker Cyclization by Tandem Electrochemical Oxidation and Copper Catalysis

Xile Hu, Xiangli Yi

In oxidative electrochemical organic synthesis, radical intermediates are often oxidized to cations on the way to final product formation. Herein, we describe an approach to transform electrochemically generated organic radical intermediates into neutral p ...

Mechanistic implications of lanthanum-modification on gold-catalyzed formic acid decomposition under SCR-relevant conditions

Oliver Kröcher, Davide Ferri

The use of formate-based ammonia precursors as alternatives to urea in the selective catalytic reduction (SCR) process requires that formic acid released upon their thermolysis in the hot exhaust is rapidly decomposed to carbon dioxide. This work aims at t ...

Nickel-Catalyzed Regioselective Hydroalkylation and Hydroarylation of Alkenyl Boronic Esters

Xile Hu, Srikrishna Bera

Metal hydride catalyzed hydrocarbonation reactions of alkenes are an efficient approach to construct new carbon-carbon bonds from readily available alkenes. However, the regioselectivity of hydrocarbonation remains challenging to be controlled. In nickel h ...

Amide synthesis via nickel-catalysed reductive aminocarbonylation of aryl halides with nitroarenes

Xile Hu, Chi Wai Cheung, Marten Leendert Ploeger

Aminocarbonylation of aryl halides is one of the most useful methods in amide synthesis, but nitroarenes have not been used as a nitrogen source in this method even though they are more economical and accessible than anilines. Reported here is the developm ...

Copper-Catalyzed Three-Component Carboazidation of Alkenes with Acetonitrile and Sodium Azide

Jieping Zhu, Qian Wang, Ala Bunescu, Minh Tu Ha

A copper-catalyzed three-component reaction of alkenes, acetonitrile, and sodium azide afforded gamma-azido alkyl nitriles by formation of one C(sp3)-C(sp3) bond and one C(sp3)-N bond. The transformation allows concomitant introduction of two highly versat ...

Decarboxylative Alkynylation and Cyanation of Carboxylic Acids using Photoredox Catalysis and Hypervalent Iodine Reagents

Jérôme Waser, Franck Le Vaillant

Alkynes and nitriles are important functional groups that serve as versatile building blocks in organic synthesis and find applications in material and medicinal sciences. A convenient and straightforward access to both classes of compounds under mild cond ...

Direct amidation of esters with nitroarenes

Xile Hu, Chi Wai Cheung, Marten Leendert Ploeger

Esters are one of the most common functional groups in natural and synthetic products, and the one-step conversion of the ester group into other functional groups is an attractive strategy in organic synthesis. Direct amidation of esters is particularly ap ...
